The Big River™ Dry Bags are a durable, strong and abrasion resistant option that uses a 420D nylon fabric with a TPU lamination. If your idea of outdoor recreation involves rugged water sports like kayaking, canoeing, rafting, or motorcycle touring, these are the perfect storage bags to keep your gear dry. A white interior laminate affords greater visibility, and hypalon lash loops allow secure stacking or attachment to watercraft, motorcycles and other equipment. The hypalon roll-top closure does not wick water, and the Field Repair Buckles can be replaced in seconds with just a Philips screwdriver.

  • TPU laminated fabric with 10,000 mm hydrostatic head
  • Super strong and abrasion-resistant 420D Nylon fabric
  • Waterproof, double-stitched, reinforced, tape sealed seams
  • Hypalon lash loops for secure attachment or stacking
  • Waterproof hypalon roll-top closure does not wick moisture
  • Oval base resists rolling - stays where you put it
  • Features the patent-pending 3/4in (20mm) Field Repair Buckle with stainless steel pins
  • Suitable For Paddle Sports - The tough 420 D nylon ripstop face fabric is durable and UV resistant. Just apply reasonable caution in sharp and abrasive environments.
  • Waterproof - The body of the dry sack is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure of any dry bag.
  • Easy To Transport - Rolled up, they take up very little space. In use, the multiple lash points and double ‘D’-Rings offer plenty of attachment points for a carry strap.
